9 Claims.

This invention relates to machines for cutting and folding cloth labelsor the like and has particularly to do with labels for application tothe corners of sheets or towels or the like.

The objects of the invention are:

First, to produce a new and improved apparatus for cutting ofi labels ofthe above specified character and folding over the corners to provide alabel which slips over the corner of a towel or sheet and may be sewedin place by a single line of stitching running diagonally across thecorner.

Second, to provide such a machine in which the label is severed from alabel strip and is grasped by label feeding and holding jaws having afold form thereon of a triangular shape, which jaws feed the label tofolding devices.

Third, to provide such an apparatus which is simple in construction andin operation and which may be operated inexpensively.

Fourth, to provide fold forms and folders that may be employed withlabel cutting and folding machines already existent.

Further objects and advantages pertaining to detail and economies ofconstruction and operation will appear from the description to follow.

A preferred embodiment of my invention is illustrated in theaccompanying drawings, in which:

Fig. 1 is a perspective view of my improved machine.

Fig. 2 is a partial plan view showing the operating parts of themachine.

Fig. 9 is a plan view of a label of the type to be operated upon by themachine beforefolding.

Fig. 10 is a perspective view of the finished folded label.

Referring to Fig. 1, I there show a label cutting and folding machinewhich is of the general type of that shown in Patent No. 1,528,511granted March 3, 1925, to Martin Rosenthal and myself for Label cuttingand folding machine. It is unnecessary for purposes of this applicationto describe the operation of such machine in detail and I will refer tothe operation in general only.

The machine is mounted on a suitable base I 5 and a strip of labels 2 isfed from a supply roll 3 to a cutting knife 4. Label feeding and holdingjaws 5 grasp the label and advance it past the cutting knife 4 where itis set, the label having first been balanced by any suitable balancingmeans such as the foot 6 or by a balancing means such as that shown inmy Patent No. 1,984,657, issued December 18, 1934, for Apparatus forcutting and folding labels.

After the individual label has been severed from the strip 2, jaws 1feed it to a chute 8 or any suitable packing means.

The apparatus is driven by a suitable drive shaft 9 and is so operatedthat the holding and feeding jaws 5 grasp the end of the label strip 20and advance it through the cutter to the position shown in dotted linesin Fig. 2. The cutter then operates, severing an individual label whichis operated upon by folding means. The label holding jaws are withdrawnfrom the folder and 25 are moved around the cutter back to the positionshown in full lines in Fig. 2 to repeat the operation.

When the label holding and feeding jaws 5 advance to grasp the label,the jaws l grasp the folded label, and when the cutter 4 opens and thejaws feed the label strip through the cutter, the jaws 1 feed the labelto the position shown in dotted lines in Fig. 2, and when the jaws 5 and1 are moved to the left as in Fig. 2 to withdraw them from the folder,the label is scraped from the jaws 1 by means of the member H).

In my invention, I provide a fold form H on the upper one of the pair ofjaws 5. This fold form is of triangular shape as shown at H and theupper sides of its edges are beveled as at l3.

The fold form on the jaws is disposed so that as the jaws grasp theindividual labels for feeding, the triangular fold form is disposedabove and transversely of the individual label and the apex ll of thetriangular iold form is located substantially at the edge of theindividual label.

The severed label is then fed to a bed I5 which is recessed at IE toreceive a folder H. The folder 11 has a triangular notch therein and isso disposed that when the jaws 5 feed the label past the cutter the foldform i2 is disposed on the bed [6 above and in register with thetriangular notch [8 in the fold form I1.

The fold form i1 comprises a flat metallic member it which is suitablybolted on an arm 20 with bolts II. The arm 24 is pivoted at 22 on aslide "and is apertured at 24 to receive a bolt 25 having thereoncollars! and 21 between which is located a coiled spring 2| held inplace by the collars which are in turn held in place by a nut 29 and thearm 20. The spring 28 is a compression spring no mally tending to holdthe folder in a depressed position with the top of the member I!substantially flush with the bed It.

Means are provided for raising the folder past the fold form if. Whenthe holding jaws B with the label are positioned above the folder, themember l9 passes up pastfthe foldform if as shown in Fig. '7, foldingupthe corner 30 of the label 3|. The label M has a face 32 on which atrade-mark or other 'device may be reproduced and the corners 30 maycarry other notations. As shown in Fig. 10,-the label is madespecifically for use with sheets, one corner indicating the number ofinches of the width of the sheet and the other side indicating that thefigure represents the length. The fold form I! covers the back of theface 32 and the corners 30 are the portion bent up.

I The folder I1 is raised by means of a plunger to the position shown inFig. 7.

33 which contacts a bolt 34 through the arm 23.

. This bolt is screw threaded in the arm as shown in Fig. 3 and isprovided. with ali'nurle'd adjusting knob 35 and a look not 33. Theplunger 33 is provided with a cam follower 31 by means of which theplunger is raised to raise the folder it After the folder has beenraised to the position shown in Fig. '7, it is advanced over the edge ofthe fold form, bending the. corner 33 of the label to the position shownin Fig. 8 and creasing the same. The spring 28 holds the portion I 9 ofthe folder i8 yieldingly against the label which is folded around thefold form I 2 as shown, and heat is applied by means of the gas Jets 38.

The advancing of the folder is effected by a bell crank 39 having avertical arm 40 slotted at 4| to engage a pin 42 on the slide 23.A'horizontal arm 43 has a cam follower 44 and 9. raising of this arm 43moves the folder back from the fold form, whereas-a lowering of the arm43 forces the folder l8 to the position shown in Fig. 8.

A horizontal arm 45 is provided on the bell crank lever and has pivotedthereto a connecting rod 46 with a pin 41 and a knurled adjusting nut 48contacting a compression spring 43 which normally tends to raise the arm45 and advance the folder to the position shown in Fig. 8.

A cam slide 50 is provided having a cam 5i forengaging the cam follower31- and a cam 53 to engage the cam follower 44. These cams are sodisposed that as the slide 50 slides toward the front as in Fig. 1,impelled by the cam 54 on the drive shaft 9, the cam 5i first engagesthe cam follower 31 and raises the folder to the position shown in Fig.7. Thereafter the cam follower 44 rides down on the cam 53, permittingthe spring 49 to force the folder I 3 to the position shown in Fig. 8.

The plunger 33 is connected by coacting engagement with lever 55 whichis pivoted'at one end at 53 and has the cam follower 31 at its otherend. I

A spring 51 holds thecam slide 50 against the cam 54, causing it.toreturnas the machine completes its cycle and causing the folder l8 toassume the position of Fig. 6 preparatory to receiving another label.

The device just described is timed to operate after a label has beensevered and fed to the position shown in the dotted lines in Fig. 2, theoperation is effected automatically, and the foldingjaws 3 are thenwithdrawn to'take another label. a

It will be seen that the particular fold form can be substituted for thefold forms on the general type of machine here described and that theparticular folding apparatus can be easily substituted for the foldingapparatus illustrated on the machines inthe above mentioned patents.
